This invention relates to oil feeding systems for hydro-carbon burnersand has for its object a system adapted to filter and prepare the o-ilfor combustion in a burner used in connection with smelting furnaces orother high temperature furnaces. f

It has for its object a system which is adapted to thoroughly filterthecrudeoil before it is admitted to the burner and that is so arrangedthat the sediments or refuse resulting from the filtering process may bereadily removed when desired.

A further object is a heating of the oil to prepare vit forvolatilization and' mixing with the air. This heating arrangement is soarranged that heating the oil in no way interferes With the feedingapparatus and so that the temperature is under the control of theoperator of the furnace.

Inthe drawings z-Figure 1, is an elevation of the piping forming the oilfeeding system. Fig. 2, is a vertical section of the filter, thefurnace, the stack which surrounds the filter and the connection lwiththe furnace. Fig. 3,. is a detail of the support for the heat-Vent gate,Viewed from the left of Fig. 2 with the union removed.

A, is the furnace built of refractory brick ywhich has an inclosingshell 1, to which is `bolted. a pipe union 2 that connects the heat-.vent 3 with the aperture 4 in the furnace wall. This laperture is linedwith a metal lining 5. The heat-vent 3v at -`its outer end turns andenlarges, forming a stack 6. This stack is adapted to contain afiltering tank 7 which kcomprises a pair of cylindrical tubes screwedtogether. It will be noted that the vent 3 is bolted to theunion 2 andit may be detached, and dropped to secure access to the filter. The cap8 screws over the top of the upper tube and the plug 9 screws into thebottom of the lower tube. The oil is introduced into the bottom of thefilter through the induction pipe 10 and it flows out of the filterthrough the eduction pipe 11. These ,pipes 10 and 11 screw into the plug9 and cap 8, respectively. The interior of the tank 7 is filled Withafiltering substance. I prefer to use a section of hair 12 at both thetop and bottom. The Vspace intervening befilter material and in thisarrangement for' coarser thanV thesteel Wool. The section of hair at thebottom of the filter is located at a position where most of the sedimentdrops or sifts through. The steel wool is located at the center andforms the smaller interstices of the two filtering materials, butinasmuch as it is located at center it -is in no danger of clogging theeduction or induction pipes and interfering with t-he fiow of oil or theaction of the pumps, it being understood that the oil is pumpedthrough4v the filling material under pressure, there being a pressure ofabout twent -five pounds to the square inch. This a ords force to sendthe crude oil, which I prefer to employ, through the small intersticesof the filtering materlal which detaches nearly all the sediment andimpurities therefrom.

at the bottom. This is so that the oil can leave the top withoutcarrying with it sediment or impurities that have collected in thefilter. Such sediments and impurities is taken through from top tobottom', some of the impurities that have collected in the Abottom arequite apt to be carried into the eduction pipe.

It will be noted that I have provided a threaded aperture 14 in the sideof the lower tubulai member into which screws a plug 15. 'lhis plug canbe removed and access had to the filter for removing the sediment.

The heat-vent 3 is provided with an eX- teuding piece 16 at the endWhere it is bolted to the pipe 2. This extending piece is slotted at 17and in this slot runs a winged screw 18 that is screwed into the gate19. This gate serves as a control for the heatvent 3. By loosening thescrew the gate may be ralsed and lowered as the screw travels in theslot and by tightening the screw upon the extension piece, the gate issupported in any desired position of adjustment. Some of the hot gasesof the tween these sections is filledwith steel wool as indicated at 13in Fig. 2. I employ .this

the reason that the hair is considerably It will be noted that Iintroduce the oil p settle toward the bottom and when the oil interiorlof the` furnace are abstracted through the heat-vent pipe and pass outinto the stack 6, enveloping the oil filter 7 and are free to` passoutat the o-pen top into the stack. It will readily be understood thatby regulating the position ofthe gate 19 that aconstant temperature maybe maintained, or any iuctuatingptemperature that is desired. Theintensity of the' heat inv the stack isat alltimes indicated by athermometer 20 on the side ofthe stack.

. The oil is brought to the induction pipe' by piping 21, part of whichis ordinariiy cut out by the cutout valve 22 and the flow of oil isthrough the meter branch 23, which carries it through the oil meter 24.I locate the oil meter on the pipe line so that it is operated upon bythe oil before the same is hea-ted, as the heated oil has a tendency tointerfere with the operation of the meter. The cut-out valve may beopened and the meter branch 23 out outby closing .either of the valves354 and 36. The cut-out valves may be closed and the induction pipe `l()broken in two, by unscrewing the coupling 39. This allows the droppingof the-stack to reach the filter. Y A

The eduction pipe vl1 extendsI away ,horizontally vfrom the top of t-hefilter, thence turns in 'a downward direction and drops to a pointbelowthe burner 25. In the downward drop of the eduction pipe 11, a cut-0Hvalve 26 for the burner is located. The burner feed pipe 27 joins theeduction pipe 1l at a point below the burner and Ileads up from belowinto' the burner. This drop of the feed pipes below the burner, so thatthey feed the burner from below,has ay distinct purpose. Itwill be notedthat the coupling 28 that joinsthe feed pipe 2T with the eduction pipe11 has a flush lvalve 29 so that it mayfbe readily flushed. This is totake off any, of the impurities or sediment which have escaped thefilter and which 'naturally tendy to collect in this loop of the pipingbelow the burner.

The burner 25 is controlled by a valve 30 and fed 'with the oxygennecessary for combustion by the air .pipes 31 and 32, but ina-smuch asthe construction of the burner and the supply of air to it is not partof this invention, I have not described them. 1
